God, I'm tired so please forgive any spelling mistakes or typos.
DD is 16mo. Normally a bright, happy, chattery and laid back baby and an absolute delight to deal with. I look forward to her waking up and I feel sad when I have to put her down at night. Its lovely.
But recently in the last 2 weeks its like her evil twin has come to stay.
She hyperactive and constantly moving. If shes not doing anything in particular she'll just spin in circles whilst shrieking 'weeeeeee!'
The whining. Oh. Dear. LORD the whining. Its constant. She'll bring us a toy whilst whinging but whinge if we take it, dont take it, play with it, dont play with it. We've hidden so many of the buggers its like a treasure hunt every damn day. Shes surprisingly articulate for her age, is starting to form basic sentences and usually communicates what she wants very well so I dont know where the noise like a rusty fridge motor came from.
Nappy changes are like a game of 'kick mummy in the tit as fast as your little legs can rotate' all whilst shrieking with laughter.
'No' is apparantly the funniest word in the world. Anything sharp or electrical is the best toy in the world. Everyone other than Mummy or Daddy is her best friend.
Tantrums have started. Usually over banana's. Or the fact that I'm looking at her 
She used to sleep through the night 7pm-8am, occasionally waking at 5am for a quick re tuck-in but the past 14 nights has been waking screaming blue murder up to 9 times a night. Doesnt seem to be a reason, just wants a cuddle which we've been happy to oblige with but now we're getting very little sleep, and our evenings are a joke. I've tried exhausting her, shortening her midday naps, getting her up earlier, CIO and just plain pandering to her every time.
She gets overexcited by the daftest things. A squirrel will be in the garden and she is suddenly like a whirlwind of energy and begins to hit me in the face if Im nearby. I calmly remove her fist from my face and look away from her, but it seems to excite her further.
But then she looks at me all cute with her big blue eyes and I see my little girl again for half an hour. Sometimes she beams up at me and blows me a kiss and I think 'lies, all lies!'
Can this be the start of the terrible twos? Is it just one of those silly little phases she'll grow out of suddenly one morning? I feel like I'm going mad and it's getting to the point that I dont want to be around her :( Its doesnt appear to be teething, shes always shown very obvious signs when each one of her 14 teeth have come through. My fiance has been off work for 3 weeks with a serious chest infection and is undergoing tests for immune deficiencies, I did wonder if having both of us around is causing her to act up.
Anyone have any similar experiences or advice?
